Description
Technical Field
The invention belongs to the field of automatic watering of plants such as flowers and the like, and relates to an automatic watering device, in particular to an automatic watering device which utilizes solar energy to heat air in a container, realizes automatic water pumping, water storage and periodical watering through air pressure change generated by air expansion and contraction, and specifically relates to an automatic watering device with a solar energy pneumatic pump.
Background
The green plants can not be separated from sunlight and water, and proper illumination and water are provided according to the growth rule of the plants, which is a necessary condition for the normal growth of the plants. The transpiration of the big plants is enhanced in the sun illumination intensity in sunny days, and the consumed water is much; the sun illumination intensity is low in cloudy days, the plant transpiration is weakened, and the consumed water is less. The water consumed by plant transpiration mainly depends on the root system to absorb the water in the soil, the plant will wither or even dry and die due to water shortage because of summer inflammation and long-time water shortage in the soil, but if the water in the soil is too much and the ventilation is poor for a long time, the root system of the plant is short of necessary oxygen to cause root rot and root retting, and the plant will wither, so the watering principle of growing flowers and vegetables is that the plants are dry and wet, the surface layer of the soil is dry and permeable by one-time watering, but not watering every day or watering after the soil is completely dry and permeable. However, in actual life, flowers wither and wither because people return early after busy work and cannot water for a long time when traveling outdoors. For this reason, various automatic drip irrigation watering devices appear, among them CN105104128 (university of beijing forestry) 2015, 12 months and 2 days, a kind of automatic drip irrigation watering device for potted plants is disclosed, the water storage tank needs to be placed at a high place, the related components such as sensors and controllers need power supply, the related drip irrigation device has a complex structure and high manufacturing cost, and the device can not simply and effectively solve the watering problem of the household green plants such as potted flowers and the like.
Disclosure of Invention
The working principle of the invention is to utilize the property of expansion with heat and contraction with cold of a common object, and the expansion with heat and contraction with cold of the gas under the same temperature change condition is more obvious than the expansion with heat and contraction with cold of the solid and the liquid. When the closed container is exposed to illumination intensity (a solar light source or an incandescent light source) and environment temperature changes, the temperature inside the container changes due to energy conversion and heat exchange, the internal pressure changes due to the expansion and contraction of air inside the container, and according to an ideal gas equation, the temperature T, the volume V and the pressure P of the gas have a change relation of P1V1/T1= P2V2/T2When the pressure is constant, the volume is proportional to the temperature, and when the volume is constant, the pressure is proportional to the temperature. The pressure difference between the inside and outside of the container can push water flow (air when no water flow exists in the pipeline, the difference is that the water flow in the pipeline has water level height pressure difference, the height pressure difference of the air can be ignored) in the pipeline connected with the container to flow into or out of the container, when the temperature in the container rises and the air expands, the positive pressure difference pushes the water flow to flow out of the container, and the water flow can flow along the pipeThe water flow is sucked into the container from the pipeline by negative pressure difference when the air is contracted when the temperature in the container is reduced, and the water flow can be sucked from a lower part along the pipeline. When water flows into or out of the container, the volume and pressure of air in the container are changed continuously, and the water stops flowing when the pressure inside and outside the container reaches balance. The temperature and the air pressure in the container change in a circulating and reciprocating manner along with the alternation of sunrise, sunset and day and night, and the water flow continuously flows into the container and then flows out of the container. The temperature of the air in the sealed container rises after the sealed container is illuminated by light, the temperature rise amplitude and the illumination intensity form a positive relation, through experimental tests, when the weather is clear at normal temperature, the highest temperature in the sealed container of a single-layer structure directly illuminated by sunlight can reach 60 ℃ (333K) and can be higher than 30 ℃ (30K) than the lowest temperature of 25 ℃ (298K), when the pressure intensity is unchanged, the volume change can reach 30/298 and is about 10%, when the volume is unchanged, the pressure intensity change can also reach 10%, the pressure intensity change corresponds to 0.1 standard atmospheric pressure under normal pressure, and the corresponding height of a water column is 100 cm.
